Temperature-Tunable Entangled Photon Source for Multiplexed Time-Resolved Fluorescence on a Nanophotonic Platform

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ayantika Sengupta, Ayantika Sengupta, , , | Summary: Compact, scalable, and multiplexed fluorescence lifetime sensors are of great interest for point-of-care diagnostics. However, current solutions either lack broad-range wavelength-tuning capabilities or involve complex optical setups that hinder miniaturization. On-chip entangled photon sources offer a promising alternative […]

SLICE: SPT-CL J0546-5345 — A prominent strong-lensing cluster at $z=1.07$

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Joseph F. V. Allingham, Joseph F. V. Allingham, , , | Summary: Massive galaxy clusters act as prominent strong-lenses. Due to a combination of observational biases, cluster evolution and lensing efficiency, most of the known cluster lenses lie typically at $z_lsim0.2-0.7$, with only a few prominent […]

Ruling out dominant electron scattering in Little Red Dots’ Rosetta Stone using multiple hydrogen lines

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Matilde Brazzini, Matilde Brazzini, , , | Summary: The majority of Little Red Dots (LRDs) hosting Active Galactic Nuclei (AGN) exhibits broad H$alpha$ emission, which recent studies propose originates from scattering off free electrons within an ionized and dense medium embedding the Broad Line Region (BLR), rather […]

The Atacama Cosmology Telescope: High-redshift measurement of structure growth from the cross-correlation of Quaia quasars and CMB lensing from ACT DR6 and $textitPlanck$ PR4

Kavli Affiliate: Anthony Challinor | First 5 Authors: Carmen Embil Villagra, Carmen Embil Villagra, , , | Summary: We measure the amplitude of matter fluctuations over a wide range of redshifts by combining CMB lensing observations from ACT DR6 and $textitPlanck$ PR4 with the overdensity of quasars from Quaia, a $textitGaia$ and $textitunWISE$ quasar catalog. […]

The THESAN-ZOOM project: Mystery N/O more — uncovering the origin of peculiar chemical abundances and a not-so-fundamental metallicity relation at $3<z<12$

Kavli Affiliate: Roberto Maiolino | First 5 Authors: William McClymont, William McClymont, , , | Summary: We present an analysis of metallicities and chemical abundances at $3<z<12$ in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity relations (MZR) are already in place at $zapprox12$ and evolve slowly ($sim$0.2 dex increase for […]

KELPS: A Framework for Verified Multi-Language Autoformalization via Semantic-Syntactic Alignment

Kavli Affiliate: Yi Zhou | First 5 Authors: Jiyao Zhang, Jiyao Zhang, , , | Summary: Modern large language models (LLMs) show promising progress in formalizing informal mathematics into machine-verifiable theorems. However, these methods still face bottlenecks due to the limited quantity and quality of multilingual parallel corpora. In this paper, we propose a novel […]

Ion-rich acceleration during an eruptive flux rope event in a multiple null-point configuration

Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Melissa Pesce-Rollins, , , | Summary: We report on the $gamma$-ray emission above 100~MeV from the GOES M3.3 flare SOL2012-06-03. The hard X-ray (HXR) and microwave emissions have typical time profiles with a fast rise to a well-defined peak followed by a slower decay. The […]

Ion acceleration in Fermi-LAT behind-the-limb solar flares: the role of coronal shock waves

Kavli Affiliate: Nicola Omodei | First 5 Authors: Alexander Warmuth, Alexander Warmuth, , , | Summary: We investigate the relationship between the gamma-ray emission measured with Fermi-LAT and radio signatures of coronal shock waves in four behind-the-limb (BTL) solar flares. All events were associated with metric type II radio burst. Both start and end times […]

Multi-modal Mutual-Guidance Conditional Prompt Learning for Vision-Language Models

Kavli Affiliate: Xiang Zhang | First 5 Authors: Shijun Yang, Shijun Yang, , , | Summary: Prompt learning facilitates the efficient adaptation of Vision-Language Models (VLMs) to various downstream tasks. However, it faces two significant challenges: (1) inadequate modeling of class embedding distributions for unseen instances, leading to suboptimal generalization on novel classes; (2) prevailing […]

JVLA Measurement of Grain Size in the Compact Dust Ring around Class I Protostar WL 17

Kavli Affiliate: Ruobing Dong | First 5 Authors: Jun Hashimoto, Jun Hashimoto, , , | Summary: The maximum grain size in protoplanetary disks is a critical parameter for planet formation, as the efficiency of mechanisms like streaming instability and pebble accretion depend on grain size. Even young class 0/I objects, such as HL Tau, show […]
